MICHAEL A. MCOARRON, OF DETROIT, MICHIGAN, ASSIGNOR OF TVVO-THIRDS TO THEODORE P. BYRAM, OF SAME PLACE.

CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 366,418, dated July 12, 1887,

Application filed February 3. 1887. Serial No. 226,369. (No model.)

To aZZ whom, it may concern:

Be it known that I, hIICHAEL A. MeCARRoN, of Detroit, in the county of Wayne and State of Michigan, have invented new and useful Improvements in Car-Brakes; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form a part of this specification.

This invention relates to certain new and useful improvements in car-brakes, the object of the invention being to construct a brake wherein the brake-shoes are simultaneously closed upon a brake pulley secured upon the axle.

The invention consists in the peculiar arrangement of the brake-shoes, in combination with the operating levers and rods, all as more fully hereinafter set forth.

Figure 1 is a perspective view showing my improved device applied to the axles of a streetcar. Fig. 21s a vertical sectional elevation showing arrangement of brake shoes, levers, and springs. Fig. 3 is a plan.

In the accompanying drawings, which form a part of this specification, A A represent the axles of a car, to which are rigidly secured the brake-pulleys B.

O are hoods, one being placed over each pulley B, said hoods resting upon the axles in proper bearings, preferably made in two parts, that will admit of their being easily adjusted to the axles without rendering it necessary to remove the trucks or of jacking up the carbody. These hoods are connected together by a suitable bar, D, to which is pivotally secured the brake-lever E, the ends of which are connected in the usual manner to the brake staffs.

F and G are brakeshoes pivotally secured near their upper ends in the hoods C. To the sides of the shoes G are pivotall y secured the links or levers H, one end of such links being connected by means of a bifurcated pull-rod, I, to the brake-lever E.

J are pullrods connecting the lovers H with the shoes F.

In the top of the hood 0 is secured a spring,

K, the ends of which bear upon the upper ends of the brake-shoes, and compel the latter to assume their normal positions free from contact with the pulleys B when the brake-staffs are released.

By this construction and arrangement of parts it will readily be seen that, the brakestaffs being operated in the usual manner, the the pull-rods I and J compel the shoes F and G to simultaneously advance toward the brake pulleys, and, if properly hung, will simultaneously come in contact therewith. Sufficient 6 force being applied will, by frictional contact between the brake shoes and pulleys, stop the rotation of the latter, and thus stop theinertia of the car. Upon releasing the brake-staffs the springs compel the shoes toassume their 6 original positions.

What I claim as my invention is 1. In a ear-brake, the combination, with the axles A, of the pulleys B, hoods 0, connectingbar D, brake-lever E, shoes F and G, levers H, and pull-rods I and J, substantially as and for the purposes set forth.

2. In a car-brake, the COlllblllZLtlOl'l,\Vihll the axles A, of the pulleys B, hoodsO, connectingrod D, brake lever E, shoes F and G, levers H, pull-rods I and J, and springs K, the parts being constructed, arranged, and operating substantially in the manner and for the purposes described.

MICHAEL A. MOGARRON.
